ASSA Locker Hasps for Padlock-Operated Lockers
ASSA locker hasps allow lockers, cabinets and storage doors to be secured with a separate user-supplied padlock. They provide a simple mechanical alternative to built-in keyed, coin-operated or electronic locker locks.
Two principal body lengths are available. Short ASSA locker hasps suit doors up to 16 mm thick, while the longer ASSA 492831 hasp suits doors up to 22 mm thick. Selecting the correct model depends on the door thickness, handing, door preparation, catch and intended padlock.

How an ASSA Locker Hasp Works
When the padlock is removed, the hasp and internal catch can be turned through 90 degrees so that the locker door can be opened or closed. Fitting a padlock prevents the catch from rotating and secures the door.
Users can normally provide either a suitable key-operated or combination padlock. This removes the need for the site operator to issue an integrated locker key, although a procedure may still be required for abandoned padlocks or locked lockers.
Choosing a Padlock for an ASSA Hasp
The padlock shackle must fit through the hasp and provide enough internal clearance for the padlock body to close correctly.
- Use a 5–7 mm shackle diameter with the ASSA hasps for doors up to 16 mm thick.
- Use a 5–8 mm shackle diameter with the ASSA 492831 hasp for doors up to 22 mm thick.
- Allow at least 19 mm of internal shackle clearance.

Door Preparation and Catch Selection
Standard ASSA locker hasps use an 18 × 22 mm double-D door preparation. This is also used by many ASSA cam locks, which can simplify some replacement and conversion projects.
The catch is selected separately. Its length, offset, orientation and fixing position must match the locker door and frame. A compatible door cut-out does not guarantee that the existing catch will operate correctly with the new hasp.

Locker Compatibility
ASSA hasps may be used on suitable laminate, timber, metal or composite locker doors where the door thickness, preparation and fixing arrangement match the selected model.
Compatibility should be confirmed from measurements rather than the locker brand alone. Check:
- Door material and thickness
- 18 × 22 mm door preparation
- Right- or left-hand operation
- Catch length, offset and orientation
- Frame engagement
- Padlock shackle dimensions
Where a hasp is fitted into a round opening in a timber or laminate door, a suitable reinforcement or conversion plate may be required to form and support the double-D preparation.
ASSA Hasps for Leisure and Changing-Room Lockers
Padlock-operated hasps are commonly considered for swimming pools, leisure centres, gyms and changing rooms because they require no batteries, wiring or integrated user key.
Suitability for a wet, humid or chemically cleaned location depends on the exact hasp model, its component materials, the locker door, catch, fixings and level of exposure. Confirm the complete specification before installing a hasp in a chlorinated or corrosive environment.
